Calibration board diagrams

CGB-020

Note: CGB calibration boards are made of carbon fiber material and designed in an integrated method, so they do not require additional adapters.

CGB-035, CGB-050

Note: The difference between CGB-020 and CGB-035/050 lies in mounting hole arrangements:
CGB-020 has one type, while CGB-035/050 has another.

OCB calibration boards

Note: OCB calibration boards are made of glass material, have no mounting holes, and are intended solely for EIH calibration.

BDB calibration boards

Note: BDB calibration boards have acrylic surfaces and metal adapters.

Diagrams of calibration circles arrangement and spacing

CGB calibration boards

A CGB calibration board has 5 rows and 4 columns of calibration circles, arranged asymmetrically.

BDB calibration boards

Similar to CGB calibration boards, a BDB calibration board also has 5 rows and 4 columns of calibration circles, arranged asymmetrically.

OCB calibration boards

An OCB calibration board has 11 rows and 9 columns of calibration circles, arranged symmetrically.
